Why are cheek ephithelial cells always moist?

Asked by Chetan Bhardwaj | 23rd Dec, 2013, 11:12: PM

Expert Answer:

Cheek cells secrete a continuous supply of mucin, the principal element of mucous. In combination with the salivary glands, the mucin maintains a moist environment in the oral cavity.

A sufficient moisture content must be continually sustained in order to aid enzymes in softening food, facilitate swallowing, and initiate the process of digestion.
